This article reveals trend of HIV/AIDS in Benue State, north central, Nigeria. The method adopted was a descriptive analysis of the HIV epidemiology in Nigeria using Benue State as a case study. This review article was through the report of periodic epidemiological surveys of Antenatal Clinic (ANC) sentinel surveys, National HIV and AIDS and Reproductive Health Surveys (NARHS), Nigeria Demographic Health Surveys (NDHS), Integrated Biological and Behavioural Surveillance Surveys (IBBSS), National Agency for the Control of AIDS (NACA), United Nations Agency for AIDS (UNAIDS) and Benue State Agency for the Control of AIDS (BenSACA). This study reveals that, out of the current 1.9 million people representing 1.4% (15-49 years) living with HIV in Nigeria, Benue State accounts for 188,482 representing 4.9%. Thus, Benue State is now second as against the previous reports which have consistently placed Benue State as the state with highest prevalence of HIV/AIDS in Nigeria since the beginning of the pandemic in the country. The new prevalence estimates by states, however, still categorize Benue state and six other states with high prevalence of 2.0% and above. The national prevalence among females is significantly higher at an estimated 1.9% than the male prevalence estimated at 0.9%. In conclusion, the effort of peer educator trainers, awareness of HIV/AIDS on radio and television programs and efforts of other stake holders who are working towards ending the AIDS epidemic have been the secret behind the compliance of Benue people towards spreading news of AIDS not the virus. However, much still need to be done to consolidate on this success.
Exposure to toxic inorganic Arsenic (iAs) in areas endemic for urogenital schistosomiasis may confer increased risk for bladder cancer. The severity of the adverse effects of iAs however depends on its metabolism, which is highly variable among individuals. Genetic polymorphism in Arsenic (+3) Methyl Transferase enzyme, accounts significantly for these variations. To investigate the relationship of AS3MT gene polymorphisms and Arsenic metabolism to schistosomiasis and/or associated bladder pathology, 119 individualsfrom Eggua in southwest Nigeria were recruited for this study. Screening for schistosomiasis and bladder pathology was done by microscopy and ultrasonography respectively. Wagtech Digital Arsenator was used to assess total urinary arsenic concentrations and thus determine the level of arsenic exposure. The single nucleotide polymorphism AS3MT/Met287Thr T>C (rs11191439) was genotyped using Alelle-Specific PCR. Of the participants who tested positive for schistosomiasis, 33.3% exhibited bladder pathology. Total urinary arsenic concentration in 80% of the participants was above the WHO limit of 0.05mg/L. The Met287Thr allelic distribution conformed to the Hardy-Weinberg equilibrium (X2= 0.161, P> 0.05). Observed allelic frequencies were 0.96 and 0.04 for wild-type T and mutant C alleles respectively. There was no significant relationship between AS3MT SNP, arsenic concentrations and schistosomiasis associated bladder pathology. In conclusion, the community is highly exposed to arsenic, although with a possible genetic advantage of increased AS3MT catalytic activity. However, we see the need for urgent intervention as inter-individual differences in arsenic metabolism may influence the bladder pathology status of individuals in the community. And although urogenital schistosomiasis is waning in Eggua, it is not known what synergy the infection and high arsenic exposure may wield on bladder pathology.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
